Girl's Behavior

My boyfriend eats like a pig

I love cooking for him and appearently he likes eating too. But when he eats it's often quite disgusting.

He stuffs everything in his mouth as if we were in a rush and then half of it falls out. He has gravy all over his face, What did his parents teach him?

When we go out he eats normal but when we are at home he acts like child and driving me insane

Anyways, how should I go about it? Should just go hey baby you eat like a pig, please stop doing that or should I be a little more sublte about it?
